AI Technical Summary
Technical Problem
Existing electric axial flux machines for motor vehicles face challenges in manufacturing cost and assembly complexity due to lengthy tolerance chains and the need for additional assembly aids.
Method used
The stator and housing of the axial flux machine are positioned directly via integrated or separate positioning means, such as moldings or protrusions, eliminating the need for further assembly aids and shortening tolerance chains.
Benefits of technology
This direct positioning method enhances manufacturing efficiency, reduces costs, and optimizes installation space utilization, enabling easier assembly and more efficient component alignment.

Abstract
An electric flux machine for use within a drive train of a hybrid or fully electrically driven motor vehicle includes a stator and a rotor separated from the stator by an air gap, wherein the stator is accommodated in a pot-like annular housing having a housing base extending in the radial direction, wherein the housing base extends through the air gap between the stator and the rotor and the housing is closed by a housing cover on the side axially opposite the housing base, wherein the housing cover has at least one first positioning means projecting in the axial direction out of the housing cover or projecting in the axial direction into the housing cover, which first positioning means co-operates with a corresponding second positioning means on the stator in such a way that the position of the stator is fixed relative to the housing cover.
